giving rise to exact renormalization group transformations with periodic and aperiodic behaviour
is proposed. Several of these transformations are displayed explicitly. … [1], and others [2] have
demonstrated that certain frustrated Ising models on hierarchical lattices [3,4] possess (exact)
renormalization group (RG) transformations with periodic and aperiodic trajectories [5]. McKay
et al. have suggested that the chaotic region corresponds to a spin-glass phase, providing a …
